Copper Arabic coin [решено]

Hello everyone,
Would anyone be about to help identify this small (16 mm) coin? Looks like Arabic script, seems similar to some inscriptions on Abbasid coins. Nice desert patina, irregular flan, weighs 2 g, appears to be copper. Any help would be much appreciated!

Looks like Abbasid

Thanks, Petrus, much appreciated! Can anyone who knows Abbasid coins identify the issuer (presuming it's not anonymous) and mint? I've looked at a lot of examples of Abbasid fals, but haven't seen any exactly matching this coin.
